Hey,
I did what you did in your so called tutorial.
I work in the It-Section for years now and I have a lot of knowledge in this sector. I must say, that it works for me, but the way how you describe the steps to do are so god damn bad, I can´t believe it.
I have professional knowledge and sometimes I dont know what to do.
For example: “B: You readback your BIOS using the command ‘AfuEfix64.efi backup.rom /O’”
Many of the users don´t know what to do there. I made it in efi mode, but most other people will struggle.
Anyways, nice way you discovered, but really but presentation, considering a small mistake could convert people´s devices to trash.
Cheers
